Not clear what you mean by this. Are you asking how arrays as column values in relational databases are indexed? I think it depends on the specific relational database and what types of queries it supports on array values.

I think the answer is usually one-to-many relationships.

However, I am not sure if JSON or JSONB columns in PostGRES can be indexed. (That is, no Foreign keys needed.)
